"Sensors are everywhere once you look!" he says.
Raven stops by the window. "What do you notice? Some sensors watch. Some listen."
Nova hums softly. "Here is a hint," she says. "A sensor only picks up signals. Who decides what to do with them?"

A sensor only picks up signals. Software and people decide what to do with them.

Super week, explorer! Tomorrow your family goes on a sense walk.
